retina

The retina is the innermost layer or coating at the back of the eyeball, which is sensitive to light and in which the optic nerve terminates. Every claim on this page comes from the Leumas anatomy graph and carries its source.

What the retina is

The retina is the innermost layer or coating at the back of the eyeball, which is sensitive to light and in which the optic nerve terminates. The atlas records it as a tissue at the tissue scale in the human body.

Where the retina is

It sits in the head, within the nervous and sensory systems. Positioned deliberately as part of this species body plan.

What the retina connects to

The atlas records 22 typed relationships for it, across 9 kinds of connection. part of eye, eyeball of camera-type eye and material anatomical entity, and 3 more.

Supply and innervation

Arterial supply: central retinal artery. Venous drainage: central retinal vein. Innervation: cranial nerve II and optic tract.

Also called

Also recorded as inner layer of eyeball, retina of camera-type eye, tunica interna of eyeball, Netzhaut and retinas. Searching any of those names reaches this page.

Questions

Where is the retina?

It sits in the head, within the nervous and sensory systems. Positioned deliberately as part of this species body plan.

What does the retina connect to?

Part of: eye, eyeball of camera-type eye, material anatomical entity, nervous system, posterior segment of eyeball and camera-type eye.

Is the retina the same in other species?

Leumas holds the same relationship vocabulary for every species it carries, so where another dataset records this structure you can put the two side by side on /compare.
